Awareness About Keratoconus and Its Relation With Eye Rubbing: A Cross‐Sectional Study in Riyadh

Health Science Reports, Volume 9, Issue 4, April 2026.
ABSTRACT Background Keratoconus is a progressive eye disease affecting the cornea, the clear dome‐ shaped structure at the front of the eye. In keratoconus, the cornea thins and bulges outward into a cone shape, leading to loss of visual acuity. The aetiology of keratoconus remains unclear, but it involves both genetic and environmental factors.

Immediate Postoperative Decentration of a Biologic Corneal Inlay Managed With Tomography‐Guided Repositioning: A Case Report

Clinical Case Reports, Volume 14, Issue 3, March 2026.
Immediate postoperative Pentacam corneal tomography revealing inferior‐temporal decentration of the biologic corneal inlay on the axial curvature map. ABSTRACT Biologic corneal inlays can rarely present with immediate postoperative decentration, which can be subtle and difficult to detect clinically. Real‐time tomography allows precise early diagnosis,
